Como Hacer Un Respaldo De Archivos En Windows 7

So I used oculus link with the cable and had perfectly fine audio 1 week ish ago. Well today there is no audio coming from the headset. My PC had no clue there is audio capability in the device. I do not mean the audio is disabled. I checked the disabled devices and it is not there. I re-installed everything. Forgot the quest 2 and found it again. And there is still no "oculus virtual audio device" When there was a week earlier. All I want is for my PC to find it again.
